Tudor and KH domain-containing protein (TDRKH)

Participates in the primary piRNA biogenesis pathway and is required during spermatogenesis to repress transposable elements and stop their mobilization, which is vital for the germline integrity. The piRNA metabolic process mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and regulate the methylation and subsequent repression of transposons.

Required for the last steps of primary piRNA biogenesis by participating in the processing of 31-37 nt intermediates into mature piRNAs. May act in pi-bodies and piP-bodies by transferring piRNA precursors or intermediates to or between these granules.
